One of the most sensitive and important issues in the design and implementation of tunnels is due to the large amount of investment, the choice of the method of drilling and the choice of the type of maintenance system suitable for it. In this paper, the analysis of maintenance systems has been considered and the characteristics of the maintenance system have been considered and evaluated. The proposed Tunnel Fell Model is the result of the proposed maintenance systems for medium-heavy frames with a range of 1.1 to 1.6 and a wide bolt with a distance of 1.4 to 2.2 and a width of 20 cm with a thickness of 20 cm in the crown and the walls with the bolt of choice rock Became
